WebThe word chirality is used as a term to describe a molecule whose enantiomers are non-superimposable on their mirror images. A chiral molecule that contains a single stereogenic center may exist in an enantiopure form or as a mixture of enantiomers in varying ratios. WebFeb 13, 2024 · Chirality essentially means 'mirror-image, non-superimposable molecules', and to say that a molecule is chiral is to say that its mirror image (it must have one) is not the same as it self. Whether a molecule is chiral or achiral depends upon a certain set of overlapping conditions.
